  watchdog: s3c2410_wdt: use exynos_get_pmu_regmap_by_phandle() for PMU regs (2024-02-25 11:39:25 +0100)

----------------------------------------------------------------
Samsung SoC driver changes for v6.9, part two

1. Extend Exynos PMU (Power Management Unit) driver being also the
   syscon to main system controller registers block, to support Google
   GS101.  The Google GS101 has PMU registers protected and writing is
   available only via SMC.  The Exynos PMU will register its own custom
   regmap for such case of mixed MMIO+SMC.

2. Rework Samsung watchdog driver to get the regmap to PMU block not
   via syscon API, but from the Exynos PMU driver.  This is necessary
   for the watchdog driver to work on Google GS101.

[PATCH PULL v6.9 3/3] ARM: dts: samsung: exynos4412: decrease memory to account for unusable region

[Krzysztof Kozlowski]

From: Artur Weber <aweber.kernel@gmail.com>

The last 4 MiB of RAM on those devices is likely used by trustzone
firmware, and is unusable under Linux. Change the device tree memory
node accordingly.

The proprietary bootloader (S-BOOT) passes these memory ranges through
ATAG_MEM; this change allows us to have the correct memory ranges
without relying on ATAG_MEM.
